How A Fish Finder Operates
A fish finder has one core feature – to locate the fish, enhancing your fishing experience by allowing you to catch more fish. It has two parts: a display screen and a transducer.
- Display screen – you can mount it on a board or carry it around. The purpose of the display unit is to display the information you need.
- Transducer – with two main functionalities: emitting high-frequency sound waves by converting electrical into sound energy, and receiving back the reflection and converting it into electrical data.
Different Types of Fish Finders
Mountable Fish Finder
Consists of a mountable transducer and display unit. Depending on the mounting type, you can attach the fish finder to the boat temporarily or permanently.
Portable Fish Finder
With this type, you get a small display unit and a portable transducer with temporary mounts. This type often operates on batteries.
Read more about portable fish finders here: Portable Fish Finders.
Wireless Fish Finder
- A new type consisting of a floating, wireless transducer that transmits data to your smartphone via mobile data or Wi-Fi.
What Is A Good Price For A Fish Finder?
Important Considerations When Choosing a Fish Finder
Transducer
The transducer is an essential element for any fish finder – a device converting energy from one form to another. It converts electrical energy into sonar waves, and vice versa. Three factors are most important: mount type (also dictating material), cone angle, and frequency.
Transducer Cone Angle
It is the width of the sound wave emitted into the water for your boat. The wider the cone, the larger the covered area. The deeper the sound wave goes down, the lower the intensity projected back to the transducer. Less accuracy produces image distortions.
Transducer Frequency
It refers to the frequency of the sound wave emitted by the transducer. The higher the frequency, the wider the cone angle. If you want to fish in shallow waters, higher frequencies are better as lower frequencies are better for deep waters.
CHIRP Sonar and CHIRP Transducers
CHIRP (Compressed High-Intensity Radiated Pulse) is the most sophisticated sonar technology today. Standard sonar sends 1 frequency at a time. If you want two different frequencies, you will need two different transducers.
Read more about sonar fish finders here: Best Sonar Fish Finder.
Display Unit
Often, choosing a display is like choosing an underwater fishing camera. It’s also important to consider some technical factors like how well it presents the data. Another really important feature is the resolution of the screen.
Screen Resolution
Screen resolution refers to how many pixels a screen will display. The more pixels, the more details, and the smoother image.
Scanning/Imaging Methods
Side-imaging fish finder allows scanning wider areas and seeing schools in great detail. Yet, the side-scan sonar won’t produce effective imaging in deep waters. This is where a down-imaging sonar comes in. It uses a single transducer emitting a powerful sound wave and is better for monitoring deep water.
Portable VS Mounted
It’s true that a portable fish finder that is comparable to a fixed fish finder will offer less quality. So, it’s best to focus on the main feature – portability. If you use the fish finder for smaller boats or kayaking, then the portable is a better choice.
A fixed/mounted finder is better if you want advanced technology. They are more stable, reliable, and a better choice for high-speed boats. They are more consistent and you won’t need to re-tweak the settings.
GPS Integration
We are all familiar with GPS technology nowadays. Many models also offer GPS/Chartplotter feature, which provides various benefits:
- Navionics and Charting: GPS provides easier navigation to prime fishing grounds or finding your way back to dry land.
- Water Temperature: You might find fishing spots where cold and warm waters meet. The GPS feature will help you navigate between water temperatures.
- Location Saving: You can save locations like prime fishing spots, dangerous areas, etc.
- Depth Finder: GPS models offer both mapping and charting features, so you get more accurate readings of the land.
Using a GPS—or Chartplotter—fish finder will be a different experience. Here are some tips you can use:
- Buoys: used to mark different water depths and shipping lanes on water.
- Contour Lines: These lines show you the topography below the water.
- Shipwrecks: Some GPS units can highlight shipwrecks locations on the map.
- Seabed: Some fish species hang out at specific depths, and GPS tracking will offer an accurate reading of the seabed’s layout.
If GPS is a must for your device, check out our buyer’s guide for best fish finder gps combo.
Water Resistance
If you use the fish finder on an open vessel, then water resistance will be an important factor. Check JIS or IPX ratings on the product’s specifications. An IPX rating of 4 means the device is safe from water, which won’t be enough if you are on a kayak.
FAQ
What Is A Fish Finder?
A fish finder is a device using a sonar technique to find fish location underwater. It emits high-frequency sound waves and “catches” the reflecting wave to determine depth.
What Is GPS Feature In a Fish Finder?
Some models offer GPS, and such models are chart plotter fish finders. The GPS will allow viewing the location on a map. It adds extra features like saving different locations and more accurate charting of the bottom.
What Are The Different Types of Fish Finders?
There are fish finder models based on several different factors:
- Portability
- Scanning method
- Frequency
Also, there are new technologies introduced every year that improve fish finders’ accuracy. Technologies like livescan and 3D scans improved the down-scan and side-scan methods.
How Do I Read The Fish Finder?
Here are important things to consider:
- The hard bottom in most models displays as a blue line covered by yellow
- Any objects suspended from the bottom might or might not be a fish
- A ball shape is usually a bait ball. Larger objects around the ball are usually predatory fish.
What Frequencies Are Common For Fish Finders?
Fish finder transducers operate at ultrasonic frequencies from 50kHz to above 200kHz. Some can reach above 400kHz. The higher the frequency, the more detailed the results. Yet, the higher the frequency, the less depth it can cover.
Are Fish Finders Waterproof?
Some transducers are waterproof, but some aren’t. In most applications, there’s no need for the display unit for water resistance, but there are various waterproof units available. They are useful if you are kayaking or fishing on an open vessel.
How Can I Install The Fish Finder?
Portable fish finders won’t need any physical installation. They only need software calibrations and adjustments. For mounted/fixed units, at least the transducer must be mounted on the boat, and the process will depend on the mount type.
Can We Use a Fishfinder on a Kayak?
It is pretty common since a fish finder can locate various hazards like rocks and logs, which increases the safety of your kayaking. We can mount the transducer either within the hull, over the side, or through the scupper holes.
Read more about fish finders for kayaking here: Fish Finder For Kayaking
What Is The Best Brand To Choose?
The most popular brands available today include Lowrance, Garmin, Humminbird, Deeper, and Furuno. Different brands offer different features suiting a certain fishing style.
Conclusion
Fish finders are an affordable solution to improve your haul. While there are many different types and sets of features, it’s best to figure out your needs first. The products we have reviewed above, as well as the buying guide, should help you make a better decision in buying your perfect fishfinder.
